I remember very well the day of this accident. It was barely a month later after another major aircraft accident with the TAP aircraft coming from Lisbon to Madeira that killed most of the passengers, on a third attempt to hit the runway.
A month later, this Swiss plane didn’t manage to get to Madeira airport and fell over sea but near shore. Some managed to survive by swimming.
The accidents both happened in very bad weather conditions. It was a black Christmas.
